MASSMUTUAL CORPORATE INVESTORS 2000 ANNUAL REPORT G R O W T H | S T R E N G T H | D I V E R S I T Y MASSMUTUAL CORPORATE INVESTORS INVESTMENT OBJECTIVE AND POLICY The Trust's investment objective is to combine the stability of current income offered by fixed income investments with the opportunity for growth offered by capital gains. To fulfill that objective, the Trust invests in fixed income securities, securities that can be converted into equities, and equities. The majority of these securities are in the form of private placements, meaning that they are not available to the general public. Many of these investments consist of senior or subordinated debt issued by companies that have a need for growth capital or who are being acquired in leveraged transactions. A number of these securities are considered to have a higher risk than investment grade securities, because the companies involved are either smaller and/or contain a higher level of leverage. The Trust is managed on a total return basis. Based on change in net asset value with reinvested dividends, the Trust was ranked #1 for the three-and ten-year periods ending December 31, 2000 among the closed-end bond funds tracked by Lipper, Inc. Lipper, Inc. ranked the Trust #4 for the five-year period ending December 31, 2000. Dividends are paid to shareholders quarterly in January, May, August and November. The Trust intends to distribute nearly all of its net income to shareholders each year. Dividends are paid in cash, unless the shareholder elects to participate in the Dividend Reinvestment and Share Purchase Plan. In this report you will find a complete listing of the Trust's holdings. We encourage you to read this section carefully for a better understanding of the Trust. We cordially invite all shareholders to attend the MassMutual Corporate Investors Annual Meeting of Shareholders, which will be held on April 20, 2001 at 2:00p.m. in Springfield, Massachusetts. _______________________________________ MASSMUTUAL CORPORATE INVESTORS IS A CLOSED-END INVESTMENT COMPANY, FIRST OFFERED TO THE PUBLIC NEARLY 30 YEARS AGO AND IS LISTED ON THE NEW YORK STOCK EXCHANGE. 1 MASSMUTUAL CORPORATE INVESTORS [PHOTO] [PHOTO] ROBERT E.

Past performance is no indicator of future results. 2 The S&P Industrial Index is a capitalization-weighted index of stocks designed to measure the performance of the industrial sector of the Standard and Poor's 500 Index (R) (the S&P 500 Index (R) minus financials, utilities and transportation stocks). The index does not incur expenses and cannot be purchased directly by investors. 3 The Lehman Brothers Government/Corporate Bond Index is an unmanaged measure of major U.S. Government and investment grade corporate bonds with more than one year remaining until the scheduled payment of principal. The index does not incur expenses and cannot be purchased directly by investors. 2 To Our Shareholders I am pleased to share with you MassMutual Corporate Investors' Annual Report covering the year ended December 31, 2000. In a particularly stormy year for the markets, we are pleased the Trust was able to end the year with an annual total rate of return of 7.28% as measured by the change in net asset value with reinvested dividends. The Trust's net assets as of the end of 2000 were $178,130,497. Quarterly dividends were at $.45 per share in May and were increased to $.47 per share in July, October and December. Including the extra dividend of $.90 per share in December, dividends totaling $2.76 per share were distributed in 2000. The net asset value per share of the Trust decreased slightly in 2000 to $20.74 from $22.00 in 1999. REVIEW OF 2000 The year 2000 brought an end to the longest economic expansion in our nation's history. Instead of the debate over whether the millennium began in 2000 or 2001, 2000 will be remembered as the year when the Internet suddenly became a place of business - and evaluated using more traditional measures. The year began with an incredible surge in the stock market, in particular in the high-tech and biotech sectors. The first bad news of the season came from on line retailers, whose holiday business was somewhat less than expected. Then the Federal Reserve, in an attempt to slow the economy, raised rates incrementally through May. The market responded with steep declines. The Internet bubble burst, as IPOs began to fail, companies began laying off employees or just shutting down entirely. The NASDAQ, home to most publicly traded high tech stocks, experienced the most significant annual drop in its history, plunging more than 39% by the end of the year. In contrast, the S&P 500 was relatively calm, losing just over 9%, yet it was its worst return since 1977. The Dow Jones Industrial Average broke a 9-year winning streak, falling over 4%. Growth stocks, defined as the stocks of those companies expected to grow faster than the economy in general, as a category, were hit very hard, because the category includes so many high tech companies. As a result, funds that focused on growth stocks tended to perform poorly in 2000. Bonds fared far better. Interest rates, while rising somewhat, stabilized in the last half of the year. Total return on long-term Treasuries went from an 8% loss in 1999 to a 20% gain in 2000. The Lehman Brothers Government/Corporate Bond Index returned 11.84% and the Merrill Lynch High Yield Bond Index lost 5.10%, still better than stocks. _______________________________________ IN A PARTICULARLY STORMY YEAR FOR THE MARKETS, WE ARE PLEASED THE TRUST WAS ABLE TO END THE YEAR WITH AN ANNUAL TOTAL RATE OF RETURN OF 7.28% AS MEASURED BY THE CHANGE IN NET ASSET VALUE WITH REINVESTED DIVIDENDS. 3 MASSMUTUAL CORPORATE INVESTORS FOR THE 5-YEAR PERIOD ENDED DECEMBER 31, 2000, THE TRUST RANKED #4 OUT OF THE 375 CLOSED END BOND FUNDS TRACKED BY LIPPER, INC. o MassMutual MassMutual Corporate Investors (Based on earnings and change in net asset value) o S&P Industrial Stock Index o Lehman Brothers Government/ Corporate Bond Index ------------------------------------------------- Total Annual Return (as of 12/31 each year) ------------------------------------------------- 40% ---- 31.04 33.77 30% ---- 23.03 27.14 25.89 20% ---- 15.42 17.12 11.84 10% ---- 2.90 9.75 9.46 7.53 7.28 0% -------- -2.15 -10% ---- -16.26 -20% ------------------------------------------------- 1996 1997 1998 1999 2000 WHAT IT MEANS TO THE TRUST How does this news relate to the activities of the Trust? Reading our investment objective, it is clear that we look for companies that provide opportunities for long-term growth. However, we have been able to limit the impact of the current market environment on the portfolio because our focus is on the everyday goods and services that are part of any economic climate. More specifically, these events comprised the highlights of the Trust's activity in 2000: The Trust experienced major gains from five separate transactions during the year. TREND TECHNOLOGIES, a manufacturer and assembler of plastic injection molded parts that we acquired in 1997, was sold to another financial buyer. We retained a small equity position as a part of the sale with a gain of $9.1 million for the Trust. We acquired MERCURY COMPUTER, a designer and marketer of high performance computer systems for computationally intense scientific and engineering applications, originally in 1987. We took our remaining gains by selling our position during the first quarter, bringing $2.1 million into the Trust. Our total gains in this security over the life of our investment were over $14 million. _______________________________________ WE HAVE BEEN ABLE TO LIMIT THE IMPACT OF THE CURRENT MARKET ENVIRONMENT ON THE PORTFOLIO BECAUSE OUR FOCUS IS ON THE EVERYDAY GOODS AND SERVICES THAT ARE PART OF ANY ECONOMIC CLIMATE. 4 [PHOTO] [PHOTO] [PHOTO] CHARLES C. MCCOBB, CFA STEPHEN L. KUHN CLIFFORD M. NOREEN VICE PRESIDENT AND VICE PRESIDENT AND VICE PRESIDENT CHIEF FINANCIAL OFFICER SECRETARY PLAYCORE,INC., a manufacturer and distributor of home playground equipment and accessories was also sold to another financial buyer. We acquired the securities in 1997 and the total gain to the Trust was $2.2 million. LATIN COMMUNICATIONS is an operator of Spanish-language media in North America that we acquired in 1998. This sale to a strategic buyer who has other interests in Spanish media properties brought a gain of $1.1 million to the Trust. HARTZELL MANUFACTURING is a provider of contract engineering, manufacturing and assembly services for a variety of industrial manufacturing companies. We acquired the security originally in 1997. When the company was sold to a third party, the Trust experienced gains of $1.9 million. These gains allowed us to essentially offset the realized losses and write-downs in the portfolio resulting from a softening in the economic climate and decline in the stock markets during the year. The year 2000 was also an important year for new investments. The Trust closed 25 deals during the year, including 21 new investments and four additions to current positions. Among the new holdings in the portfolio: o ADORN,INC., a manufacturer of wall panels, cabinets, moldings and countertops for houses and recreational vehicles. o ENZYMATIC THERAPY,INC., a manufacturer and distributor of branded natural medicines and nutritional supplements. o INTEGRATION TECHNOLOGY SYSTEMS,INC., a manufacturer of steel protective computer and network systems for industrial and office environments. o LANCASTER LABORATORIES, one of the largest laboratory testing operations in the United States. o MOSS INC., a manufacturer of large display and exhibit structures. o PLASSEIN PACKAGING,INC., a manufacturer of flexible packaging products. o SPECTAGUARD ACQUISITION LLC, the tenth largest provider of security officers in the United States. o STRATEGIC EQUIPMENT & SUPPLY PARTNERS, INC., a provider of kitchen and restaurant design, equipment fabrication and installation services. o TRONAIR, INC., A designer, engineer and manufacturer of ground support equipment for the business, commuter and commercial aviation markets. You will find details of all the Trust's holdings in the Consolidated Schedule of Investments. _______________________________________ THE TRUST CLOSED 25 DEALS DURING THE YEAR,INCLUDING 21 NEW INVESTMENTS AND FOUR ADDITIONS TO CURRENT POSITIONS. 5 MASSMUTUAL CORPORATE INVESTORS PREVIEW OF 2001 It is already clear that the Federal Reserve Board is playing an active role in working to prevent recession. In the first week of January, the Federal Reserve Board reduced rates by one half of one percent and followed by a second one half-point reduction in the last week of January. The Federal Reserve Board's action has already impacted mortgage rates, and they could drop again in anticipation of future downward movement. While the stock market seems to be responding to the Federal Reserve Board's action, it is likely that 2001 could continue to be a volatile environment. Many of the fundamental issues that characterized the downfall of Internet stocks remain unchanged. Instead of the feverish embrace that seemed to accompany any new offering, investors are sitting back and waiting for strong earnings reports - just as they would for any bricks and mortar company. With so many people wondering if they should get ready for recession or catch their breath before a new expansion, the theme for 2001 is probably "back to basics." The Trust will continue its disciplined approach of focusing on investing in companies that offer good value on a risk-adjusted basis. We believe that our investment approach has provided solid investment returns to the Trust in the past and is particularly well suited to do so in this unsettled future. Sincerely, /s/ Robert Joyal Robert Joyal President _______________________________________ THE TRUST WILL CONTINUE ITS DISCIPLINED APPROACH OF FOCUSING ON INVESTING IN COMPANIES THAT OFFER GOOD VALUE ON A RISK-ADJUSTED BASIS.

HISTORY MassMutual Corporate Investors (the "Trust") is a closedend, non-diversified investment company. David L. Babson & Company Inc.("Babson") acts as its investment adviser. The Trust commenced operations in 1971 as a Delaware corporation. Pursuant to an Agreement and Plan of Reorganization dated November 14, 1985, approved by shareholders, the Trust was organized as a Massachusetts business trust under the laws of the Commonwealth of Massachusetts, effective November 28, 1985. On January 27, 1998, the Board of Trustees authorized the formation of a wholly-owned subsidiary ("MMCI Subsidiary Trust") for the purpose of holding certain investments. The results of MMCI Subsidiary Trust have been consolidated in the accompanying financial statements. 2. SIGNIFICANT ACCOUNTING POLICIES The following is a summary of significant accounting policies followed consistently by the Trust in the preparation of the financial statements in conformity with accounting principles generally accepted in the United States of America. A. VALUATION OF INVESTMENTS: Valuation of a security in the Trust's portfolio is made on the basis of market price whenever market quotations are readily available and all securities of the same class held by the Trust can be readily sold in such market. Nearly all securities which are acquired by the Trust directly from the issuers and shares into which such securities may be converted or which may be purchased on the exercise of warrants attached to such securities will be subject to legal or contractual delays in or restrictions on resale and will therefore be "restricted securities". Generally speaking, as contrasted with open-market sales of unrestricted securities which may be effected immediately if the market is adequate, restricted securities can be sold only in a directly negotiated transaction to a limited number of purchasers or in a public offering for which a registration statement is in effect under the Securities Act of 1933. The value of restricted securities, and of any other assets for which there are no reliable market quotations, is the fair value as determined in good faith by the Board of Trustees of the Trust (the "Trustees"). Each restricted security is valued by the Trustees at the time of the acquisition thereof and at least quarterly thereafter. The Trustees have established guidelines to aid in the valuation of each security. Generally, restricted securities are initially valued at cost at the time of acquisition by the Trust. Values greater or less than cost are used thereafter for restricted securities in appropriate circumstances. Among the factors ordinarily considered are the existence of restrictions upon the sale of the security by the Trust; an estimate of the existence and extent of a market for the security; the extent of any discount at which the security was acquired; the estimated period of time during which the security will not be freely marketable; the estimated expenses of registering or otherwise qualifying the security for public sale; estimated underwriting commissions if underwriting would be required to effect a sale; in the case of a convertible security, whether or not it would trade on the basis of its stock equivalent; in the case of a debt obligation which would trade independently of any equity equivalent, the current yields on comparable securities; the estimated amount of the floating supply of such securities available; the proportion of the issue held by the Trust; changes in the financial condition and prospects of the issuer; the existence of merger proposals or tender offers affecting the issuer; and any other factors affecting fair value, all in accordance with the Investment Company Act of 1940. In making valuations, opinions of counsel may be relied upon as to whether or not securities are restricted securities and as to the legal requirements for public sale. When market quotations are readily available for unrestricted securities of an issuer, restricted securities of the same class are generally valued at a discount from the market price of such unrestricted securities. The Trustees, however, consider all factors in fixing any discount, including the filing of a registration statement for such securities under the Securities Act of 1933 and any other developments which are likely to increase the probability that the securities may be publicly sold by the Trust without restriction. The Board of Trustees of the Trust meets at least once in each quarter to value the Trust's portfolio securities as of the close of business on the last business day of the preceding quarter. This valuation requires the approval of a majority of the Trustees of the Trust, including a majority of the Trustees who are not interested persons of the Trust (otherwise than as Trustees) or of Babson. In making valuations, the Trustees will consider reports by Babson analyzing each portfolio security in accordance with the relevant factors referred to above.Babson has agreed to provide such reports to the Trust at least quarterly. The financial statements include restricted securities valued at $176,899,997 (99.31% of net assets) as of December 31,2000 ($174,084,140 at December 31, 1999) whose values have been estimated by the Board of Trustees in the absence of readily ascertainable market values. Due to the inherent uncertainty of valuation, those estimated values may differ significantly from the values that would have been used had a ready market for the securities existed, and the differences could be material. The values for corporate public securities are stated at the last reported sales price or at prices based upon quotations obtained from brokers and dealers as of December 31, 2000, subject to discount where appropriate, and are approved by the Trustees. Short-term securities with more than sixty days to maturity are valued at fair value and short-term securities having a maturity of sixty days or less are valued at amortized cost which approximates market value. B.ACCOUNTING FOR INVESTMENTS: Investment transactions are accounted for on trade date. Dividend income is recorded on the ex-dividend date. Interest income is recorded on the accrual basis. The cost basis of debt securities is not adjusted for amortization of premium since the Trust does not generally intend to hold such investments until maturity; however, the Trust has elected to accrue, for financial reporting purposes, certain discounts which are required to be accrued for federal income tax purposes. 33 MASSMUTUAL CORPORATE INVESTORS CONSOLIDATED NOTES TO FINANCIAL STATEMENTS December 31, 2000 and 1999 Realized gains and losses on investment transactions and unrealized appreciation and depreciation of investments are reported for financial statement and federal income tax purposes on the identified cost method. The Trust does not accrue income when payment is delinquent and when management believes payment is questionable. C. USE OF ESTIMATES: The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. D. FEDERAL INCOME TAXES: No provision for federal taxes on net investment income and short-term capital gains is considered necessary because the Trust has elected to be taxed as a "regulated investment company" under the Internal Revenue Code, and intends to maintain this qualification and to distribute substantially all of its net taxable income to its shareholders. In any year when net long-term capital gains are realized by the Trust, management, after evaluating the prevailing economic conditions, will recommend to the Trustees either to designate the net realized long-term gains as undistributed and to pay the federal capital gains taxes thereon or to distribute all or a portion of such net gains. E. RECLASSIFICATIONS: Certain amounts from prior years' financial statements have been reclassed to conform with current year presentation. 3. MANAGEMENT FEE Under an investment services contract,Babson has agreed to invest for MassMutual Life Insurance Company's ("MassMutual") general account concurrently with the Trust in each restricted security purchased by the Trust. Babson, in addition to originating and sharing in the purchase of such securities, represents the Trust in any negotiations with issuers, investment banking firms, securities brokers or dealers and other institutions or investors relating to the Trust's investments. Babson provides a continuing review of the investment operations of the Trust. Babson also provides the Trust with office space and office equipment, safekeeping facilities, accounting and bookkeeping services, and necessary executive, clerical and secretarial personnel for the performance of the foregoing services. Under the investment services contract, as amended July 1, 1988, the Trust pays Babson a quarterly base rate (the "Base Fee Rate") of 5/16 of 1% of the value of the Trust's net assets as of the end of each fiscal quarter, approximately equivalent to 1.25% of the net asset value of the Trust on an annual basis, plus or minus a quarterly performance adjustment (the "Performance Adjustment") of up to 1/16 of 1% approximately equivalent to .25% on an annual basis. The Performance Adjustment is based on the Trust's performance as compared to a benchmark rate of return (the "Target Rate") equal to 5.0 percentage points plus an unweighted, arithmetic average of the rates of return on the Standard & Poor's Industrial Stock Price Index and the Lehman Brothers Intermediate Corporate Bond Index over a rolling three-year period (the "Measurement Period") comprising the twelve quarters ending on the last day of each quarter (the "Valuation Date"). The Performance Adjustment is equal to 5% of the difference between the Trust's actual rate of return over the Measurement Period and the Target Rate. If the Trust's actual rate of return exceeds the Target Rate, the Base Fee Rate is increased by an amount equal to the Performance Adjustment; if the Trust's actual rate of return is less than the Target Rate, the Base Fee Rate is reduced by the Performance Adjustment. The advisory fee payable by the Trust is equal to the Base Fee Rate (as adjusted by the Performance Adjustment) times the net asset value of the Trust as of the Valuation Date. The Performance Adjustment for the year ended December 31, 2000 was: PERFORMANCE ADJUSTMENT AMOUNT -------------------------------------------------------------------------------- March 31,2000 (0.0625%) ($128,204) June 30,2000 0.0625% 132,603 September 30,2000 (0.0625%) (126,330) December 31,2000 0.0215% 38,436 -------------------------------------------------------------------------------- Total (0.0410%) ($83,495) 4. SENIOR SECURED INDEBTEDNESS A. NOTE PAYABLE On November 5, 1993, the Trust sold to MassMutual at par a $20,000,000 Senior Fixed Rate Convertible Note due November 15, 2000 (the "Note") which accrues at 5.33% per annum. The Note holder, at its option, can convert the principal amount of the Note into common shares. The dollar amount of principal would be converted into an equivalent dollar amount of common shares based upon the average price of the common shares for ten business days prior to the notice of conversion. In agreement with MassMutual, the Note's maturity has been extended for an additional seven years from November 15, 2000. The Note is due November 15, 2007 and will accrue at 7.39% per annum. For each of the periods ended December 31, 2000 and 1999, the Trust incurred total interest expense on the Note of $1,117,500 and $1,066,000, respectively. B. REVOLVING CREDIT AGREEMENT The Trust entered into a senior unsecured,floating rate, revolving credit agreement (the "Revolver") with Fleet National Bank (the "Agent Bank") as of June 29, 2000 in the principal amount of $25,000,000, maturing on May 31, 2005. The interest rate on the outstanding revolving loan is determined for periods of one, three or six months (as selected by the Trust) and is set at an annual rate equal to LIBOR (London Interbank Offered Rate) plus 0.37%. The Trust also agreed to pay an up-front fee equal to 0.10% on the total commitment. The facility fee is 0.15% per annum of the total commitment. As of December 31, 2000, there were no outstanding loans drawn against the revolving credit facility. For the period ended December 31, 2000, the Trust incurred $19,007 in expense related to the undrawn portion. 34 CONSOLIDATED NOTES TO FINANCIAL STATEMENTS. December 31, 2000 and 1999 5.

The financial highlights for the year ended December 31, 1998 and for each year of the years in the eight-year period then ended were audited by other auditors, whose report, dated February 25, 1999 expressed an unqualified opinion on those financial highlights. We conducted our audits in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements and financial highlights. Our procedures included verification of securities owned as of December 31, 2000 by counting of securities at the custodian and confirmation of securities owned as of December 31, 2000 by correspondence with the custodian and brokers. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the consolidated financial statements and consolidated financial highlights referred to above present fairly, in all material respects, the financial position of the Trust as of December 31, 2000 and 1999, and the results of its operations, its cash flows, its changes in net assets, and financial highlights for the years then ended in conformity with accounting principles generally accepted in the United States of America. /s/ DELOITTE & TOUCHE LLP New York, New York February 9, 2001. 36 OFFICERS STUART H.

Noreen Vice President MARK B.ACKERMAN Treasurer VICTORIA FORTIER Comptroller DIVIDEND REINVESTMENT AND SHARE PURCHASE PLAN MassMutual Corporate Investors offers a Dividend Reinvestment and Share Purchase Plan. The Plan provides a simple way for shareholders to add to their holdings in the Trust through the receipt of dividend shares issued by the Trust or through the reinvestment of cash dividends in Trust shares purchased in the open market. A shareholder may join the Plan by filling out and mailing an authorization card to Shareholder Financial Services, Inc., the Transfer Agent. Participating shareholders will continue to participate until they notify the Transfer Agent, in writing, of their desire to terminate participation. Unless a shareholder elects to participate in the Plan, he or she will, in effect, have elected to receive dividends and distributions in cash. Participating shareholders may also make additional contributions to the Plan from their own funds. Such contributions may be made by personal check or other means in an amount not less than $10 nor more than $5,000 per quarter. Whenever the Trust declares a dividend payable in cash or shares, the Transfer Agent, acting on behalf of each participating shareholder, will take the dividend in shares only if the net asset value is lower than the market price plus an estimated brokerage commission as of the close of business on the valuation day. The valuation day is the last day preceding the day of dividend payment. When the dividend is to be taken in shares, the number of shares to be received is determined by dividing the cash dividend by the net asset value as of close of business on the valuation date, or if greater than net asset value, 95% of the closing share price. If the net asset value of the shares is higher than the market value plus an estimated commission, the Transfer Agent, consistent with obtaining the best price and execution, will buy shares on the open market at current prices promptly after the dividend payment date. The reinvestment of dividends does not, in any way, relieve participating shareholders of any federal, state or local tax. For federal income tax purposes, the amount reportable in respect of a dividend received in newly-issued shares of the Trust will be the fair market value of the shares received, which will be reportable as ordinary income and/or capital gains. As compensation for its services, the Transfer Agent receives a fee of 5% of any dividend and cash contribution (in no event in excess of $2.50 per distribution per shareholder.)
